摘要： As system for clamping an rotary tool accessory disc or blade to an output shaft of a rotary tool comprising a cam clamping mechanism and a clutch assembly wherein the cam clamping mechanism comprises: a head element threadably engageable with the output shaft at a location axially outward of the accessory disc; a cam rotatably connected to the head element and rotatable between a clamped and unclamped position, wherein the clamped position the cam exerts a compression force axially inward against the accessory disc or blade; and wherein the clutch assembly comprises: at least one first type of disc located coaxially on and keyed to the output shaft; at least one second type of disc located coaxially on the output shaft and in planar parallel contact with the first type disc; and an inner washer having an internal bore, the inner washer located coaxially on the output shaft, axially outward of and surrounding the first type disc and the second type disc, the inner washer keyed at the internal bore to the second type of disc such that rotation of the second type of disc imparts rotation to the inner washer.

摘要： An improved circular saw blade designed for cutting fiber cement workpieces, which are becoming more and more prevalent on the construction site, includes a PCD/carbide tip mounted in the rim of a saw blade at six, rather than the usual four locations, equally spaced around the blade. The tips are mounted adjacent a relatively large-diameter, semi-circular gullet, which itself is preceded by a chip and dust minimizer. The minimizer includes several alternating hills and valleys formed in the rim of the saw blade, each hill and valley having the same radius, producing a sinuous array essentially centered on the rim of the blade. It has been discovered that such a dust and chip minimizer reduces the level of dust and chips produced by the blade and clears the same from the kerf generated in the blade-workpiece interface. Ideally, all of the parameters and relief angles for the surfaces on the saw blade tip can be generated by cutting an array of such tips from a large-diameter blank of PCD fused to a layer of tungsten carbide, and by mounting the tips onto the blade in such an orientation as to present, preferably, a negative hook or rake angle to the workpiece.
摘要翻译：一种设计用于切割纤维水泥工件的改进的圆锯片，其在施工现场变得越来越普遍，包括安装在六叶轮边缘的PCD /硬质合金刀头，而不是通常的四个位置，等间隔围绕刀片。尖端安装在相对较大直径的半圆形齿槽附近，其前身是碎屑和粉尘最小化器。最小化器包括形成在锯片的边缘中的几个交替的山丘和谷，每个山谷和谷具有相同的半径，产生基本上以叶片的边缘为中心的弯曲阵列。已经发现，这种粉尘和碎屑最小化器降低了由叶片产生的灰尘和碎屑的水平，并且从刀片 - 工件界面中产生的切口将其清除。理想情况下，锯片尖端表面的所有参数和仰角都可以通过将熔融到碳化钨层的PCD的大直径坯料切割成这样的尖端阵列，并将尖端安装到刀片以这样的方向呈现，优选地呈现与工件的负钩或前角。
